MORTAR-HOD.

SPECIFICATION forming part of Letters Patent No. 604,287, dated May 17, 1898.

Application filed August 8, 1894.

T 00% whom it may concern:

" Be'it' known that I, WILLIAM G.AVERY, of

Cleveland, in the county of Ouyalioga and State of Ohio, have invented certain new and useful Improvements in Mortar-Hods; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

The object of the invention is to provide a metal mortar-hod that is comparatively simple in construction, light, and durable, presenting an article of" this character having tight joints and smooth walls, the latter feature making it possible to quickly and thoroughly clean the hod.

With the above objects in view the inven tion consists'of a mortar-hod made of a single blank of metal substantially rectangular in shape, one end being extended at either side at obtuse angles with the sideedges and having a central portion or section terminating in a flap, the blank being bent transversely near the aforesaid end, then bent upon its longitudinal center and the central section of the end portion bent inward upon the inclined sides to form a transverse wall between said sides, after which the triangular portions extending beyond the wall are bent upon the latter and the flap or upper end of said wall turned over the edges of the adjoining material.

In the accompanying drawings I have shown the sheet-metal blank and manner of bending the same in forming my improved hod.

In the drawings, Figure 1 is a plan view of the blank, the dotted lines representing the lines upon which the said blankis bent or folded in forming the hod. Fig. 2 is aperspective view showing the first step in the formation of the hod. Fig. 3 is aperspective view illustrating the second step. Fig. 4 is a similar view of the third step. Fig. 5 is aperspective view of the completed hod.

My improved hod, as shown in Fig. 5, has

the general appearance of an ordinary wooden hod, presenting inclined side walls A A and an end wall A, which form a body triangular in cross-section and open at its top and at one end.

The invention consists in forming this particular hod of a single sheet or blank of metal,

Serial No. 519,770. (No model.)

which, as illustrated in Fig. 1, is substantially rectangular in shape, the exception being that one end isextended at either side at obtuse angles from the side edges and provided centrally with a curved extension or flap M the ends of said flap being designated by the letters M m, while the edges between the flap and corners k and o of the blank are designated by the letters Z and at. In order to simplify the description or operation of bending the blank, said blank is marked with dotted lines, upon which the bends are made. To this end a line b is drawn along the longitudinal center of the blank, meeting a transverse line (1 d at c, with the point 0 as a cen ter and one-half of line (I d as a radius, and at the side of line cl d opposite to the location of line b is described a semicircle e. Dotted lines f, g, 2', and j all radiate from point cand, crossing the semicircle, divide the space bounded by said semicircle and line (1 01 into four equal divisions 7c, Z, n, and 0, two at each side, and a central division or section M equal to any two of the aforesaid divisions. The two side edges of the blank extend beyond the line 01 d, as at 0, respectively, in the direction of and meeting lines f and j at k 0 The edges Z n of divisions Z n extend from points k 0 respectively, to the junction of lines 9 i with the semicircle e, while the flap M forms an extension of the central portion or division. It will be noted that by folding the triangle divisions at one side of the end portion of the blank upon each other they together form practically a double flap of triangular shape, and in so folding both sets of triangles at opposite sides of the central division M the latter is brought perpendicular to the base-line b and the side portions of the body of the blank brought up against the edges of said. central division, presenting double flaps beyond the latter, as shown in Fig. 3.

In the manner of bending illustrated in the drawings the blank is first bent upon the transverse line (I, then outward upon the lines f j, and inward upon the lines g t', the body of the blank being simultaneously bent upward upon the central lineb. This operation, as before, brings the central division M perpendicular to the line b, the sides ofthe body of the blank up against the side edges of said central division, and the triangular divisions 10 Z n 0 parallel with said sides, forming triangular flaps which extend beyond the' central division. Said flaps are then bent or folded upon the rear side of the central division, as shown in Fig. 4, and the flap M folded over the edges of the triangular flaps, completing the hod illustrated in Fig. 5.

It will be apparent that by the peculiar shape of the blank and manner of folding the same, as hereinbefore described, I provide a metal hod similar in shape to the ordinary wooden hod, presenting smooth walls and tight joints; and though I am aware it is notbroadly new to make a mortar-hod from sheet metal, yet the improved construction of my hod presents an improved article of manufacture possessing certain advantages over the metal hod shown in the patent to D. Nolan, No. 172,888, dated February 1, 187 6} Having thus particularly described my invention, what I claim as new, and desire to secure by Letters Patent, is-

As an improved article of manufacture, a triangular-shaped mortar-hod made up of a single blank. of sheet metal substantially rectangular with one end extended at either side at obtuse angles with the side edges and having a triangular central section terminating in a flap, said blank being bent transversely near the aforesaid end, then bent upon its longitudinal center and the said triangular central section bent inward upon the inclined sides to form a transverse wall between said sides, after which the triangular portions or flaps extending beyond the wall are bent upon the latter and the flap or upper end of said wall turned over the upper edges of the aforesaid fiaps, as herein shown and described.

In testimony whereof I sign this specification, in the presence of two witnesses, this 3d day of August, 1894.

WILLIAM G. AVERY.
